Sixty two years ago, Herbert A. Pohl, a scientist at the Naval Research Laboratory at Anacosta D.C., reported the motion of suspensoid particles by means of polarization forces in an inhomogeneous field; he termed this electrokinetic phenomenon as “Dielectrophoresis” . Since then, there has been an impressive growth in dielectrophoresis-based microdevices, as demonstrated by more than 300 papers published yearly since 2008. Dielectrophoresis is becoming one of the main pillars in the field of microfluidics due to its flexibility and great potential for integration with other techniques. The applications for dielectrophoresis have expanded from biomedical and clinical assays to environmental monitoring and water and food safety analysis.
After the great success of “Dielectrophoresis 2011” in issues 17 and 18 of volume 32 [2, 3], we decided to organize a special issue on this novel separation technique again, with the aim of disseminating the latest findings in this dynamic and fast evolving field. It is our pleasure to present you with the second installment in this series, the special issue “Dielectrophoresis 2013.”
The present special issue consists of 18 valuable contributions from research groups in USA, Europe and Asia. It is divided into four parts: (i) Fundamentals, (ii) Nanoana-lysis, (iii) Biomedical Applications and (iv) Bioanalytical Applications. The first section on Fundamentals covers two new developments in insulator-based and reservoir-based dielectrophoresis. The second section on nanoanalysis includes four contributions on dielectrophoresis of colloidal paticles, nanoparticles and electrorotation.
The third section is focused on biomedical dielectrophoresis; it starts with a review article on the future outlook in Point-of-Care applications. It also includes three valuable contributions on cell isolation and characterization, two articles on cell aggregates and islets of Langerhans, and an article on detection of DNA biomarkers and virus from blood.
The fourth and last section is focused on bioanalytical applications for analysis of proteins, DNA and virus. This section begins with a review article on protein dielectrophoresis which examines the latest developments and challenges. Two more articles focusing on protein manipulation complement this topic; an article on DNA manipulation on three-dimensional electrodes demonstrates a novel approach, followed by the last contribution that deals with manipulation of bacteriophage viruses.
We would like to express our greatest appreciation to all the contributors for their excellent articles and to all the reviewers for their hard work and support that made the special issue “Dielectrophoresis 2013” possible.
